Dayselector widget example

This code places two Elementary dayselector widgets on a window, each of them exemplifying the different widget styles.

The first of them is the dayselector in default style:

/* add a dayselector widget showing weekdays starting from Sunday */
dayselector = elm_dayselector_add(win);
evas_object_size_hint_weight_set(dayselector, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
evas_object_size_hint_align_set(dayselector, EVAS_HINT_FILL, 0.5);
evas_object_smart_callback_add(dayselector, "dayselector,changed", _changed_cb, NULL);
elm_box_pack_end(bx, dayselector);
evas_object_show(dayselector);

elm_box_pack_end
void elm_box_pack_end(Elm_Box *obj, Efl_Canvas_Object *subobj)
Add an object at the end of the pack list.
Definition elm_box_eo.legacy.c:57
elm_dayselector_add
Evas_Object * elm_dayselector_add(Evas_Object *parent)
Add the dayselector.
Definition elm_dayselector.c:469
evas_object_show
EVAS_API void evas_object_show(Evas_Object *eo_obj)
Makes the given Evas object visible.
Definition evas_object_main.c:1814
evas_object_size_hint_weight_set
EVAS_API void evas_object_size_hint_weight_set(Evas_Object *obj, double x, double y)
Sets the hints for an object's weight.
Definition evas_object_main.c:2638
evas_object_size_hint_align_set
EVAS_API void evas_object_size_hint_align_set(Evas_Object *obj, double x, double y)
Sets the hints for an object's alignment.
Definition evas_object_main.c:2650
evas_object_smart_callback_add
EVAS_API void evas_object_smart_callback_add(Evas_Object *eo_obj, const char *event, Evas_Smart_Cb func, const void *data)
Add (register) a callback function to the smart event specified by event on the smart object obj.
Definition evas_object_smart.c:1040

As you see, the default style displays the weekdays starting from Sunday.

One can select/unselect a day just by clicking on the day object. The selection toggles once it is being pressed.

For showing weekdays starting from Monday, see the second dayselector:

/* add a dayselector widget showing weekdays starting from Monday */
dayselector = elm_dayselector_add(win);
evas_object_size_hint_weight_set(dayselector, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
evas_object_size_hint_align_set(dayselector, EVAS_HINT_FILL, 0.5);
evas_object_smart_callback_add(dayselector, "dayselector,changed", _changed_cb, NULL);
elm_object_style_set(dayselector, "mon_first");
elm_box_pack_end(bx, dayselector);
evas_object_show(dayselector);
elm_object_style_set
Eina_Bool elm_object_style_set(Evas_Object *obj, const char *style)
Set the style to used by a given widget.
Definition elm_main.c:1583

The following code exemplifies the selection APIs of Dayselector:

/* Callback function when a day is clicked. */
static void _changed_cb(void *data EINA_UNUSED, Evas_Object *obj,
void *event_info)
{
char buf[256];
Elm_Dayselector_Day day;
Eina_Bool selected;
/* get which day's state is changed */
day = (Elm_Dayselector_Day) event_info;
/* get the state of corresponding day's check object */
selected = elm_dayselector_day_selected_get(obj, day);
switch(day)
{
case ELM_DAYSELECTOR_SUN: snprintf(buf, sizeof(buf), "%s", "Sun"); break;
case ELM_DAYSELECTOR_MON: snprintf(buf, sizeof(buf), "%s", "Mon"); break;
case ELM_DAYSELECTOR_TUE: snprintf(buf, sizeof(buf), "%s", "Tue"); break;
case ELM_DAYSELECTOR_WED: snprintf(buf, sizeof(buf), "%s", "Wed"); break;
case ELM_DAYSELECTOR_THU: snprintf(buf, sizeof(buf), "%s", "Thu"); break;
case ELM_DAYSELECTOR_FRI: snprintf(buf, sizeof(buf), "%s", "Fri"); break;
case ELM_DAYSELECTOR_SAT: snprintf(buf, sizeof(buf), "%s", "Sat"); break;
default: snprintf(buf, sizeof(buf), "%s", "???"); break;
}
fprintf(stderr, "%s state is %d\n", buf, selected);
}
/* End of clicked callback */
